tomcat自动关闭:A fatal error has been detected by the Java Runtime Environment

这两天项目服务器经常自己挂掉,查看了一下日志:

# A fatal error has been detected by the Java Runtime Environment:
#
# SIGBUS (0x7) at pc=0x00007ff185390840, pid=2846, tid=0x00007ff15c8a4700

根据上面的日志路径,查看了hs_err_pid2846.log:
其中有一段显示了错误的位置:

BUG参考资料:点击打开链接

尝试了一下网上给出来的解决方法,设置jdk参数:-XX:-ReduceInitialCardMarks

结果还是没有效果

最终解决方案:

把服务器tomcat引用的jdk改成1.8,项目的jdk也改成1.8

这样就解决问题了
